4 Claims. (01. 160-27) My invention relates to roll-a-way window screens, demountably attachable to a sash.

An object of my invention is to provide roller type window screens that may be mounted within the window frame at both top and bottom if desired. The said window screens having the means of being detachably secured to the bottom and top edges of the window sash thereof so that when the bottom window sash is raised, or when the top window sash is lowered, the openings between the said window sash and window frame will be closed by window screening.

A further object of my invention is to provide roll-a-way window screens, mounted on springurged rollers, so that when the said window sash is closed, the window screen will automatically roll itself awa and out of sight on the said spring-urged rollers.

A still further object of my invention is to provide a quick means of looking or unlocking the said window screen into a sealing relationship with the edges of the said window sashes.

A further object of my invention is to provide a screen-retaining moulding which is removably securable to the edge of the window sash and at the same time, in its lowered position, forms a waterproof seal with the window sill. In the said closed position the top of the said screenretaining moulding is flush with the said window sill.

A still further object of my invention is to provide a resilient seal, designed to fit over the said screen-retaining moulding, for window frames that are too badly worn to permit sealing by the said screen-retaining moulding.

A still further object of my invention is to provide a closure means, attachable to the upper edge of the lower window sash, to prevent insects from entering through the space between the said window sash and window pane while the said windows are open.

A further object of my invention is to provide roll-a-way window screens, demountably attachable to a sash, that may be economically pro-' duced in large numbers to fit any type or size of sliding windows.

Other objects and advantages embraced in my invention will be disclosed in the following description and the accompanying illustrations, in which like parts are designated by like numerals, and in which Fig. 1 is the front view of a sliding type window, with parts cut away, and showing my roll-a-way window screens attached to the sash thereof.

Fig. 6 is an enlarged vertical cross-sectional view taken substantially on line 66 on Fig. 1, and showing the locking means for releasably securing the screen to the window sash.

Fig. 7 is a top view of a portion of my invention, partly in cross section, looking in the direction of the arrows on line 1----'! on Fig. 2.

Fig. 8 is a top cross-sectional view of a portion of my invention taken substantially on line 8-8 on Fig. 1, and showing the screen guide means used in connection with my invention.

'Referring to the illustrations, my invention is generally designated 9, and consists of a length of window screen IU of either metal or plastic wire. The lower edge of the said window screen I0 is looped at H and sewed at I2 to permit a roller attaching rod l3 to be inserted therein. A number of cutouts M in the looped edge ll provide clearance for the looped ends [5 of a number of flat coil springs IE to be secured to the roller attaching rod I3; the said spring ends I5 protrude from slots I! in a hollow roller H3. The said hollow roller I8 is rotatably mounted upon a roller shaft I9; the outer ends of which are formed into flats 20 to provide holding and locking means within the slot 2| on the ends of the roller casing 22. The said ends 55 are partly cut away to permit the removal of the screen roller l8 when desirable, as shown in Fig. 3.

The said roller casing 22, together with the roller I8, are mounted upon the underside of window sill 23, or upon the top side of the top of window frame 56, as shown in Figs. 1 and 2. The said fiat coil springs l6 are mounted prewound at intervals upon the roller shaft [9, within the roller [8 and, by means of the ends l5 extending through the slots 11, provide tension to the said roller l8, causing a rotational pull in a counterclockwise direction, as shown in Fig. 3.

Since the spring ends [8 are attached by means of roller attaching rod l3 to the screen [0; therefore when the said screen I0 is. released from 3 window sash 35, or when the said window sash is lowered, the said screen Iii will wind itself upon the roller l8 within the casing 22.

A longitudinal opening 24 is provided in window sill 23 to allow the screen It to pass therethrough. The edges 25 of opening 24 are beveled to provide seating for a screen-holding moulding 26; the said screen-holding moulding 26 is provideclwith tapered sides 53 to make a sealing contact with said beveled seating 25. A central groove 2'! runs throughout the length of moulding 26, in the center of which is formed a depending flange 28. g p

Attached along the bottom edge of flange 28 is an inverted U-shaped screen-retaining-keyway 29, in which a removable key rod 3| retains the looped top edge 38 of screen IE. Thus,'by means of said removable key rod 31, the top edge of screen Hi may be quickly secured to, or removed a from, the, screen-holding, moulding 2i}. Formed on the top surface, one at either end of moulding 2filare sash attaching. wedges 32, which. are insortable. into triangularly-shaped wedge slots W33 in the two ,bottom corners of the said, window ing edge of wedge-32.

sash 36. The said sash attaching wedges 32 may be locked within the triangular wedge slots 33 by a wedge-locking means 35.

The said wedge-locking means 3 consists of 1a cylinder 37. mounted within an, opening 35 in sashes at a point in alignment withthe sloplAkeyway 39is formed in the side of wedge 32 to communicate with aslot 38 in cylinder 31. A, wedge-holding bolt it, whichis slidaoly containedin cylinder 3?, pro- ,vides the locking means withithe said keyway 39, and is held in the said lockingposition by a coil springii2 in the end of cylinder 3i, as shown inFigs.3and6. .s

By depressing and rotating .the lock manipulating extension it upon the end otsaid wedgeholding bolt ddaawedge release slot iii upon the I said boltiili is brought. into. registry with keyway SS releasingthe window sash 35 from screenholding moulding 213;; the said wedge-holding bolt til-is locked in its depressed inoperative posi- --tion by means of a bayonet lock 33 in the outer endthereof. s, -Figs. and 7 show details. of a 'closuremeans 48 provided to close the opening between window panedil and: window sash 38 when one .onboth of the window sashes are open. The said closure means fificonsists of a strip of screening, having -a rubber wiper tip fi'i', and attachedby means of metal stays 38 to the top edge of window sash 36; A screen-guide and sealing meansis illustrated in Figsl and 8. The inner side portions of ---sills thereofare badly worn, a rubber sealing cap 45 is provided to'fit over the screen-holding -rnoulding 26,'as illustrated in Fig. 4. The said rubber sealing cap means 45 is provided with overlapping edges 54 to prevent moisture or dirt from penetratinginto opening 23. .i

To use my roll-a-way window screen, the window-screen together with the roller 28 and the casing 22 -are mounted asshown in Fig.3 ontothe underside of window sill 23 when mounted .for

attachment to the lower window sash The 4 lower edge of screen I0 is attached by means of roller attaching rod l3 and spring ends IE to the said roller I8. The upper edge of the said screen if) is attached by means of key rod 3| within screen-retaining keyway 29 on screen-holding moulding 25. When released, the said screen it! will be automatically rolled upon roller l8, pulling the sealing moulding 25 into sealing contact with the beveled seating 25 in window sill 23.

The wedge-holding bolt 49 is locked in its depressed, inoperative position, allowing the window sash 36 to be lowered into a locking position with the said ash attaching wedges 32. Rotation of block manipulating extensions 34 releases may be similarly. equipped with roller screen structure and will operate in amari ner similar to t t d low r W iQW cr H The above described roll-away window screen,

, together withthe window sashes and frame,

provide a completely insect p roof screening to the windows whenopengwith the added advantage of clear view windowswith the screen rolled away and out of sight during wet weather when the windowsare closed. Thescreens are not exposed to the weather and therefore will last longer. Y g

, lvly roll-a-wa window screen, demountably 7 attached to a sash, may be attached to any type, ,wood or metal, window sash and frame, or may be manufactured therewithas aunit.
